Hyco PF100S 100L 3kW Powerflow Smart Unvented Water Heater

The Hyco PF100S is a wall-mounted 100 litre unvented multipoint water heater that stores hot water and delivers it at mains pressure to more than one outlet. Patented inlet technology keeps incoming cold water from mixing straight into the stored hot water, so more usable hot water is available.

It suits kitchens, schools, restaurants, washrooms, healthcare settings and offices, and light domestic use such as one bedroom with one shower or about 7 to 11 basins, depending on demand. Three operating modes — standard, smart and eco — plus external electronic temperature control help match output to use.

The tank is glass-lined steel with CFC-free high-density polyurethane insulation and a replaceable magnesium anode. The white powder-coated casing is slimline, connections are at the base, and an unvented accessory kit is supplied and must be fitted.
